【摘要】 阿海水电站工程枢纽由碾压混凝土重力坝、左岸溢流表孔、左岸泄洪冲沙底孔、右岸冲沙底孔、坝后主副厂房等组成,枢纽布置合理紧凑。碾压混凝土坝置于横向谷、砂岩与板岩互层状坝基岩体,横向谷互层基岩状对坝基防渗、坝肩边坡稳定有利。X型宽尾墩+跌坎+消力池的消能方式,能减小冲击和脉动,提高消能效率。更多还原

【Abstract】 A’hai hydropower project complex consists of a roller compacted concrete gravity dam,left bank overflow crest outlets,left bank bottom flood discharge and flushing outlets,right bank bottom flushing outlets,a powerhouse and an auxiliary plant at dam toe.The project complex is laid out in a rational and compact way.The roller compacted concrete dam is founded on sandstone and slate interbedded bed rock mass in a transversal valley,which is favorable to both dam foundation seepage control and dam abutment slope stability.The way of energy dissipation by type X flaring pier + step down floor + plunge pool can reduce impact and impulse,thus improving efficiency of energy dissipation.更多还原
